Eriogonum gossypinum is rare to infrequent on the foothills of the Inner Coast Ranges in Kings (Kettleman Hills) and eastern San Luis Obispo counties, with two centers of concentration in Kern County, one in the Taft area and another east of Bakersfield. The Kern County populations are the most extensive and subject to the greatest habitat destruction. The species is protected at The Nature Conservancy’s Sand Ridge Preserve near Edison.

Varieties 2 (2 in the flora). Eriogonum breedlovei is geographically isolated from the rest of the E. ochrocephalum complex, and the only member nearby is E. rosense, found at higher elevations of the Sierra Nevada. Both varieties of E. breedlovei are rare. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
